Perhaps I should list the very few things I understand about wolverine.
"Old Man Logan" is a very old man assuming he is still alive, and I dont know if he is or not. He has really bad PTSD and has brain damage from being shot in the head. He is short around 5 feet. He has retractable claws and his bones are covered in metal. He has a son who is half Japanese with the same heal factor he has. He has a genetically engineered daughter who is half mexican who also has metal coated bones.
